 DETAILED DESCRIPTION
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series, and the like.
FIGS. 1 and 2 illustrate a door 10 includes a door frame 11, a door panel 12, and a light source 30. The door frame 11 includes a top rim 111, a bottom rim 112, a first lateral rim 113, and a second lateral rim 114. The top rim 111 is opposite to the bottom rim 112. The first lateral rim 113 and the second lateral rim 114 are connected between the top rim 111 and the bottom rim 112. The top rim 111 and the bottom rim 112 are configured to be fixed within walls. The bottom rim 112 is configured to be fixed to a floor. A first guiding groove 116 is defined at a side of the bottom rim 112 opposite to the top rim 111. A second guiding groove (not shown) is defined at a side of the top rim 111 opposite to the bottom rim 112.
The door panel 12 includes a first plate 121 and a second plate 122. The first plate 121 is parallel to the second plate 122. The first plate 121 and the second plate 122 are positioned between the top rim 111 and the bottom rim 112. Two opposite ends of the first plate 121 are slidably received in the first guiding groove 116 and the second guiding groove. The second plate is fixed to the top rim 111, the bottom rim 112, and the first lateral rim 113. The first plate 121 is slidable between the first lateral rim 113 and the second lateral rim 114. The first plate 121 can overlap the second plate 122, the door 10 then being in an opened state. When the first plate 121 slides to touch the second lateral rim 114, the first plate 121 spreads with the second plate, and the door 10 is then in a closed state. The first plate 121 and the second plate 122 are made of translucent glass.
The first plate 121 includes a top surface 1211, a bottom surface 1212, a front surface 1213 and a rear surface 1214. The top surface 1211 is opposite to the bottom surface 1212. The top surface 1211 and the bottom surface 1212 are connected between the top surface 1211 and the bottom surface 1212. The top surface 1211 is opposite to the top rim 111. The FIG. 3 illustrates the top surface 1211 including an optical structure 1217. The optical structure 1217 includes a number of depressions 1218. The depressions 1218 are connected. The front surface 1213 defines a predetermined pattern 1216. As FIG. 4 illustrates, the predetermined pattern 1216 is formed by a number of pits 1219. In the embodiment, the pits 1219 are arranged to display the word “EXIT.”
The light source 30 is fixed to the top rim 111 and opposite to the bottom rim 112. The light source 30 is light emitting diode. When the door 10 is in the closed state, the light source 30 is positioned above the first plate 121, and light emitted from the light source 20 passes through the top surface 1211 to enter the interior of the first plate 212. Then the light enters the front surface 1213. When the light passes through the front surface 1213, the light is scattered at the pits 1219. Thus, the predetermined pattern 1216 is illuminated. When the door 10 is opened, the first plate 121 moves away from the light source 20, and the light is withdrawn from the interior of the first plate 121. Thus, the determined pattern 1216 is not illuminated.
FIG. 5 illustrates a door 20 in another embodiment, similar to the door 10 in FIGS. 1-4. The door frame 21 does not define the first guiding groove 115 and the second guiding groove 116. The door panel 22 only includes the first plate 221. The first plate 221 is rotationally connected to the first lateral rim 213 through a rotation shaft (not shown). The light source 23 is also fixed to the top rim 211 and opposite to the bottom rim 212. When the first plate 221 rotates to touch the second lateral rim 214, the door 20 is in a closed state, and the determined pattern 2216 is illuminated. When the first plate 221 rotates away from the second lateral rim 214, the door 20 is in an opened state, the determined pattern 2216 is not illuminated.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
